摘要

The device has a pin (4) comprising two bulges (16, 18). A maximum cross-section of one of the bulges is smaller than that of the other bulge. A narrow area (17) exhibits a width (Lr1) that is greater than or equal to widths of narrow zones. Another narrow area (19) possesses a width (Lr2) that is greater than or equal to the width of one of the zones. A portion of a back part (16b) of the former bulge exhibits a complementary form to an end zone of a socket (3). A portion of a back part (18b) of the latter bulge exhibits a complementary form to a back part of an internal cavity of the socket.
